VALVE.

The invention relates to valves and hasv for an object to provide aself-closing valve, normally retained in closed position by the actionof a iiuid and manually operative to be releasably retained in openposition.

My invention embodies among other features a valve for connection with aliquid supply and in which the force of the liquid will normally retainthe valve in closed position, while at the same time the valve can bemanually operated and moved intoopen position, means being provided forlocking the valve in open position relatively to the casing thereof.

For the purpose mentioned, use is made of a casing provided with aninlet and adapted for connection with a liquid supply, a cover forengagement with the said casing and provided with an outlet, a valveseat formed on the said cover, a valve mounted within the said casingand adapted to normally repose on the said valve seat, a shank slidablymounted in the said cover, the said shank having one end thereof securedto the said valve and the other end thereof extending exteriorly of thesaid cover and terminating in a handle, a locking pin mounted on thesaid shank and adapted to engage a shoulder in the said cover to retainthe valve in open position and a spring mounted in the casing andengaging the said valve to normally retain the valve in closed position.

Reference is to be had to the accompanying drawings constituting a partof this specification, in which similar characters of reference denotecorresponding parts in all the views, and in which- Figure 1 is a sideelevation of my device, parts being broken away to disclose theunderlying structure, the valve being in open position. Fig. 2 is avertical longitudinal sectional view of my invention, the valve beingshown in closed position.

Referring more particularly to the views, I provide a tubular casing 10having an inlet 11 and a threaded portion 12 adapted for connection witha tank or the like, a chamber 13 being provided in the casing 10 andadapted to act as a seat for an expansible Speccaton of Letters Patent.

spring 14 and a second chamber 15 being provided in the casing 10 andadapted to constitute a liquid receiving chamber as will be hereinaftermore fully disclosed.

A cover 16 is adapted for threaded connection with the casing 10 and isprovided with an outlet 17, a beveled seat 18 being formed on the cover16 adjacent that portion of the cover which is threadedly engaged withthe casing 10 so that the seat 18 will be positioned adjacent the liquidchamber 15 as shown particularly in F ig. 2. A beveled valve 19 providedwith a shank 20, is adapted to repose on the seat 18, the mentionedvalve 19 being movable within the chamber 15 and the shank 2O of thevalve 19 being encircled by an end of the expansible spring 14, theother end of which is mounted within the chamber 13 as has beenheretofore mentioned. Thus the spring 14 will normally tend to ret-ainthe valve 19 in engagement with the valve seat 18.

A valve stem 21 is secured to the valve 19 and slidably extends throughthe cover 16 with an end of the valve stern projecting exteriorly of thecover and provided with a handle 22. A locking pin 23 is threadedlyconnected with the valve stem 21 and is adapted to abut against an outershoulder 23L formed in the inner side of the cover 16 when the valve 19reposes on the valve seat 18, an inner shoulder 24 being formed on theinner side of the cover 16 in spaced relation to the shoulder 23a andadapted to receive the locking pin 23 to retain the valve 19 in openposition as will be hereinafter more fully disclosed, the cover member16 being further provided with a continuous bearing surface 24bextending from one shoulder to the other. A suitable stuiiing box 25 ismounted on the cover 16 at the place where the valve stem 21 extendsexteriorly of the cover, thus preventing any leakage of fluid from thecover 16 through the opening in the cover, having the valve stemprojecting therethrough.

Now assuming that the device described is connected to a liquid supplyby engaging the threaded portion 12 with a tank or the like, the actionof the liquid flowing into the chamber 15, combined with the action ofthe spring 14 will normally retain the valve 19 in engagement with thevalve seat 18. When it is desired to withdraw a certain quantity ofliquid from the tank, an inward pressure is exerted on the handle 22thus moving the valve 19 against the action of the spring 14 and theliquid in the chamber 15, the said valve being disengaged from the valveseat 18, thus permitting the liquid in the chamber 15 and the tank toflow outwardly tln'ough the outlet 17 as will be readily understood.When the pressure on the handle 22 is released the action of the liquidin the chamber 15 and the spring 1.4: will return the valve 19 to normalposition thus closing the opening to the cover 1G and in'eventing theoutflow of the liquid in the tank. Then it desired to withdraw a larg-eamount of liquid from the tank, the handle 22 is grasped and by pressinginwardly on the handle and turning the same, the valve 19 will bedisengaged from the valve seat 18 and the locking pin 23 will engage theshoulder Q4, thus retaining the valve 19 in open position and lockingthe same against the action of the spring 1% and the liquid in the tank,thus permitting the liquid in the tank to freely flow outwardly throughthe outlet 17. Then a suiiicient amount of liquid has been withdrawnfrom the tank, the handle 22 is simply turned to disengage the lockingpin from the shoulder 2i and the combined action of the spring 14: andthe remain ing liquid in the tank will force the valve 19 into closedposition and into engagement `with the valve seat 1S.

From the foregoing description, it will be. seen that a. device isprovided, in which the outflow of liquid from the tank can be easily andquickly controlled at all times and in which either a large or smallamount of liquid can be withdrawn from the tank without necessitating acontinued inward pressure on the handle 22.

Having thus fully described the invention, what I claim as new, is:-

In a valve, the combination of a tubular casing comprising an inletmember, and an outlet member detachably secured to the in let member,said outlet member provided with a valve seat, and having a valve stemopening in alinement with the said seat, a valve stem mountedwithin saidopening for slidable and rotary movement, a valve plug secured to theinner end of said stem and adapted to seat so as to close communicationthrough the casing upon outward movement thereof, means for normallymaintaining said valve in closed position, the outlet member beingcurved downwardly and provided adjacent the lower edge o-f the valvestem opening with. a vertical shoulder, said member having a secondvertical shoulder provided at the -upper edge of the said opening andspaced inwardly with respect to the first shoulder, said member havingalso a continuous stem-bearing surface extending from one shoulder tothe other, and a locking pin projecting laterally from said valve stemand adapted to engage the innermost shoulder to lock the valve in openposition and to engage the outermost shoulder when in closed posit-ion.

In testimony whereof I atlix my signature in presence of two witnesses.
